Add controllers for default app shortcut preferences.

- add the default app shortcut preferences to the preference screen
xml instead of creating them dynamically in the fragment.
- add controller for each of the shortcut preference.
- move the corresponding shortcut detail settings into the appinfo
package.
- add individual preference screen xml for the shortcut detail settings
instead of using the shared screen template.
